What two numbers multiply to 135 and add up to 24?

Here we answer the question: "What two numbers multiply to 135 and add up to 24?"

The answer to your question is:

9 and 15

Below we illustrate and prove that 9 and 15 multiply to 135 and add up to 24:

9 × 15 = 135
9 + 15 = 24

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 24x + 135 = 0

If so, the solution to factor the quadratic equation above is:

(x + 9 ) (x + 15)

To summarize, since 9 and 15 multiply to 135 and add up 24, you know that the following is true:

x² + 24x + 135 = (x + 9 ) (x + 15)
